Has anyone ever hunted deer? It seems like the big ones always wake up and walk straight into the wind so they can smell any dangers ahead of them. Imagine if the only direction you could move was up-wind. Man. "Hey Sherry, this is Emo EMAW, I can't come into work today because of the southerly wind. I'll just telecommute. With all the jungle cats between here and town, I'd just rather play it safe."
